TZ24 Zeunerite,

Grandview Mine, Horseshoe Mesa, Grand Canyon, Arizona

5.8x 3.5x 3.0 cm

$85

While in Tucson I found two dealers who had  small quantities of zeunerite.  Zeunerite is a scarce uranium mineral, and usually does not come up for sale as anything larger than a micromount.  This particular specimen has multiple platy crystals on matrix, the largest measuring 0.6 cm on edge.
